HAIR-CLIPPER.

SPECIFICATION forming .part of Letters Patent No. 299,580, dated June 3,1884.

Application filed January 16, 1884.

To all whom it may concern:

Be it known that I, J OSEPH KILBURN PRIEST, of Nashua, in the county ofHills borough, of the State of NewHampshire, have invented a new anduseful Improvement in Hair-Clippers; and I do hereby declare the same tobe described in the following specification and represented in theaccompanying drawings, of which- Figure 1 is a top view, and Fig. 2 alongitudinal section, of a hair-clipper embodying my invention, thenature of which is defined in the claim hereinafter presented. Fig. 3 isa top view of it as it appears without its capplate, operative spring,and its adjustable arm.

Fig. 4 is a top View of the cap-plate. Fig. 5 is a side view of theaforesaid spring, and Fig. 6 a top view of the adjustable bifurcatedarm. ldclig. 7 is a front view of the head of the han- In the saiddrawings, A denotes the stationary comb-plate, and B the reciprocatingtoothed cutter-plate. Each of these plates is provided with a series ofteeth like those of a comb, but formed as is customary in otherhair-clippers of the class to which the one herein described belongs.The cutter-plate has rectangular slots a a in it, to receive twoscrews, 1) 6, extending upward from the combplate through the cap-plate0, arranged on the cutter-plate and the head 0 of the handle D. Nuts (1,screwed on the said screws, serve with them to keep the cap-plate inplace.

The head c-a front view of which is shown in Fig. 7 is provided with atubular cylindrical neck, d, extending up from it, as shown, such headhaving within it transversely and opening through its lower side a notchor recess, e, for reception of the cutter-plate-operative lever E, whoseshorter arm f projects into a notch, g, in the cutter-plate.

The lever E has a cylindrical fulcrum, h, projecting upward from it, andhaving a .diameter corresponding to that of the bore of the neck d. Suchfulcrum, where projecting above the neck, is prismatic, or substantiallyso, toenter a corresponding-shaped opening, a, in a bifurcated arm, F,shaped as represented. A screw, is, screwed down into the prismatictenon or extension, or arranged therewith and with the bifurcated arm inmanner as shown, serves to confine them together.

(ModelJ A spiral spring, G, encompasses the neck d, the lower endportion of the said spring being inserted in a hole in the head a, whilethe upper end portion is extended into the fork of the arm F. Thisspring is to so 0perate the lever E as to cause its longer arm to movein a direction away from the handle D, in order for the lever to movethe cutter-plate backward on the comb-plate, its movement in theopposite direction being effected by pressing the longer arm of thelever toward the handle, such being usually effected by a person whilegrasping the handle and the said longer arm in one hand.

By having the tenon of the fulcrum pris matic and the mortise or holefor its reception in the bifurcated arm correspondingly shaped, the armcan be adjusted or turned apart to cause the spring to act with thenecessary power or more or'less force, as may be desirable.

From the handle an ear, Z, extends upward for the thumb of the operatorshand to bear against while grasping the handle and lever. Another ear,m, extends from the longer arm of the said lever, and is intended at thesame time to pass between the index and third fingers of the hand.

The spiral spring, to protect from accumulations of hair or dandruffiisencompassed by an elastic clasp, p, of metal.

I do not claim a hair-clipper constructed as represented and describedin the United States Patent No. 216,998, dated July 1, 1879, foralthough in common with such and various other hairclippers or analogousdevices I have a comb-plate with its supporting-handle and a movablecutter-plate and its operative lever and spring, I have to the handlethe tubular neck, and to the operative lever a fulcrum in one piece withit, and to extend up through such neck and takea bearing therein, andconnect with a bifurcated arm adapted to receive the spiral spring atits upper end or part, as described. My improvement enables the springto be taken up or adjusted to act with more or less force, as occasionmay require, and saves the necessity of having for a fulcrum a separatescrew, liable to work loose by the operation of the lever.v

I claim I11 a hair-clipper, the combination of the handle I), having thehead 0, provided with a tubular cylindrical neck, (1, thecutter-plateoperat ive lever E, having a cylindrical fulcrum, h, whichenters the neck (6, such fnlerum having a substantially prismatic neck,the bifurcated arm F, which is secured on the neck of the fulcrum, andthespring G, secured at one end to the head 0 and at the other in 1 theyoke of the arm 11, whereby the position i of the arm can he changed onthe fulcrum and 10 the tension of the spring varied, as set forth.
